03/12 EM-ABS-01 for ACU 117
8.8 Motor temperature
he temperature monitorin
is a part of the error and warnin
behavior which can be
freely configured. The connected load can be monitored by the connection of a mea-
surement resistor (motor PTC resistor / PTC ) with a temperature characteristic to DIN
44081 or with a bimetallic temperature sensor (NC contact).
The operation mode of the motor PTC port can be selected via parameter
Motor Temp.
Operation mode
570 The operation modes described in chapter "Motor Temperature"
of the frequency inverter operatin
instructions are complemented by the followin
operation modes with the extension module:
Operation mode Function
11 -
EM-MPTC:
warning only
The critical point of operation is displayed by the control
unit and parameter
Warnings 269.
12 -
EM-MPTC:
Fault shutdown
The fault shutdown is displayed by message F0400. The
fault shutdown can be acknowledged via the control unit
or the digital input.
13 -
EM-MPTC:
Fault shutdown
1 min del.
The fault shutdown according to operation mode 2 is
delayed by one minute.
14 -
EM-MPTC:
Fault shutdown
5 min del.
The fault shutdown according to operation mode 2 is
delayed by five minutes.
15 -
EM-MPTC:
Fault shutdown
10 min del.
The fault shutdown according to operation mode 2 is
delayed by ten minutes.
The function to be adjusted by parameter
Motor Temp. Operation mode 570 results in
signaling the overtemperature by the red LED of the frequency inverter, irrespective o
the selected operation modes of the control inputs and outputs.
The operation modes with error-switch-off result in the fault messa
e "FAULT" with
fault number "F0400" being displayed on the control unit KP500.
The fault message can be acknowledged via parameter
Program 34 or the lo
ic si
nal
linked with parameter
Error acknowledgement 103.
